.SPECIFICATION forming part of Letters' Patent No. 6so,eo4, dated Augusts, 189e.

Application filed September 26, 1898. Serial No. 691,887. (No model.)

To ctZZ whom, it may concern.'

Be it known that I, WILLIAM M. GOLD- THWAITE, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in Globesand Mountings Therefor; and I do hereby declare the follow-v ing to be afull, clear, and exact description of the invention, such as will enableothers skilled in the artV to which it appertains to make and use thesame.

My invention relates to a novel construction in a collapsible globe-mapand mounting therefor, the object being to provideadevice of thischaracter which can be made to occupy small space and whendistended canbe posed in any desired manner for purposes of demonstration; and itconsists in the features of construction and combinations of partshereinafter fully described and claimed.

In the accompanying drawings, illustrating my invention, Figure 1 is aside elevation of my device, showing the globe distended and in twopositions on its stand or mounting. Fig. 2 is aside elevation of thesame, showing the globe collapsed and in the position in which leastspace is occupied. Fig. 3 isa detail view in elevation, showing theconnection between the handle and the center stick of the globe. Fig. 4is a side elevation of a portion of the stand, showing'the clasp forholding the globe thereon. Fig. 5 is a top plan view of same. Fig. 6 isa sectional view on the line 6 6 of Fig. 5. Fig. 7 is a detail sectionalview showing a telescopic connection between two members of the stand ormounting. Fig. 8 is a sectional view on the line 8 8 of Fig. 7. Fig. 9is a detail view of the end of the inner telescopic member of the standor mounting. Fig. 10 is a central longitudinal section of the globe.Fig. 11 is a fragmentary detail sectional view,on an enlarged scale,similar to Fig. 10. Fig. 12 is a fragmentary central sectional viewshowing another Inanner of constructing the globe.

Referring now tosaid drawings, A indicates a globe comprising acollapsible wire frame consisting of a plurality of wires 1, mounted atopposite ends, inwhich I term umbrella-centers 2 and 3, which aremovable with relation to each other and serve to spread the wires 1 whenmoved toward each other. A covering of satin or similar fabric adaptedto assume a practically globular form is mounted over said wire frameand has a map of the earth printedthereon, said coverling beingdistended by the spreading of said wires 1.

Said umbrella-center 2 is rigidly mounted upon a rod 4, passing throughsaid frame, while said umbrella-center 3 is telescopically mounted onsaid rod or rigidly mounted on a sleeve 5, telescopically movable onsaid rod 4. The rod 4 may consist of a tube, as shown in Figs. 10and l1,and is provided at one point with a spring-catch 6, adapted to engagethe lower end of the sleeve v5 to retain the globe in its distendedposition. Said rod or sleeve 4 is made in sections, the section 7thereof being connected with the section 4 by means of the interiittingscrewthreaded sleeves S and 9, as shown in Fig. 3. The upper end of saidrod 4 is provided with an eye 10, by means of which the globe may behung. or tube 4 I mount small incandescent electric lamps 11, which areconnected with an electric circuit by means of wires 12 passing throughsaid tube 4 and out of same at any convenient point, thus enabling me toillumine said globe from the interior, which is obviously advantageous.For mounting said globe I provide a stand comprising a base B, on whicha tubular standard C is mounted., A rod 13 is telescopically movable insaid standard C and is held in any desiredl position therein by means ofa sleeve 14, mounted upon the lower end of said rod 13 and verticallyslotted at its end, thereby forming a plurality of springingers bearingagainst the inner face of said standard C, thus holding said rod inplace by friction. At its upper end said rod 13 car-A ries an arm 15,which is pivotally mounted and heldin any desired position on said rodbyV means of a set-screw 16. Said arm 15 forms one member of a clasp andis provided in its outer end with a semicylindrical recess 17, which,together with a similar recess in an arm 18, pivotally mounted onsaid-arm 15,

forms a sleeve to receive the lower end portion of the sleeve 5. Saidarm 18 is normally held in the position shown'in Fig. 5 by means of aspring interposed between said arms 15 and 18, rearwardly of the pivotof the latter, in an obvious manner. To insert the sleeve Within saidglobe and on said rod IOO 5 in said clasp, the rear end of the arm 18 ispressed against the arm l5, thus opening the clasp sufticiently toinsert said sleeve 5. In this manner, as will be apparent, I am enabledto revolve said globe on its axis and on said rod 13 as an axis and atthe same time turn it on the pivot of the arm I5 to any desired positionwithin an arc of one hundred and eighty degrees.

In Fig. l2 I have illustrated another construction of the globe in whichthe umbrellalatch is placed higher up in the inner tube and enters aslot in the outer sleeve. The latch is extended to provide anoutwardlyprojecting arm, by means of which it is released. The saidinner tube terminates on a level with the lower end of the outer tube orsleeve and is internally threaded to receive either a sleeve, by meansof which said globe can be mounted on the stand, or receives thelowersection of the handle. At the upper end of said inner tube is asmall ring, by means of which said globe is hung.

Obviously when the globe is hanging no part of the interior mechanismwill project and thereby disfigure it.

I claim as my nvention-V In a device of the kind specified, acollapsible globe comprising two relatively telescopic members eachhaving an umbrella-center mounted thereon, elastic ribs pivoted at theirends in said umbrella-centers and adapted to expand by forcing saidtelescopic members together, a cover over said ribs adapted to beexpanded to a practically globular form by the expansion of said ribs, aspring-clasp on one of said telescopic members adapted to engage theother thereof to hold said covering in its expanded position, said claspbeing provided with a lever for releasing said clasp projectingoutwardly, one of said telescope members projecting from said globe andprovided with devices for removably securing a handle thereto and afordmeans of mounting said globe revolubly in a stand, substantially asdescribed.

In testimony whereof I aiiix my signature in presence of two Witnesses.
